.ANNUNCIATOB OR INDICATOR SYSTEM.

Application filed July 22, 1921. Serial No. 486,790.

To all whom it may concern Be it known that I, SAMUEL KATz, a citizen of the United States, and resident of New York city, borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Annunciator or Indicator Systems, of which the following is a specification.

The present invention relates to annunciator or indicator systems, and more particularly to a device of this character which entails electro-mechanical mechanism.

An object of the present invention is to provide an indicator system of this character which is adapted for use under such conditions as exist in hospitals, factories, stores,

quires no skill or ,manipulation other than inserting a key in the keyhole at a local station box and withdrawing the key therefrom, the system thus being adapted for use with a key which may be carried at all times by the person and which is not left in. the key on switch box of the local station.

Another important feature of the present invention. is in the provision of electromechanical devices which are selectivelyoperated by keys of different characters to not only actuate certain indicating mechanism at the main station or office for-registering the particular local station atwhich the key .is used, but to also indicate at the mairi station or otlice the particular char- .acteristic, number or letter, by which the individual kkey is known.

The invention further aims at the'provisiofi of an annunciator system of this character which embodies a peculiar combination of electro-mechanical contrivances reducing the various circuits to a minimum in numbers and parts and which may be easily installed and easily maintained in working condition.

Briefly stated, the invention embodies a central station having a number of indicators, a selector connected to the indicators for selectively connecting the same in the mam circuit for subsequent operation and for subsequently transmitting through the main ClIClliiL'SllCh electrical impulses as are required for the transmission of the various intelligences or indications desired with respect to the selected indicator, and "a plurality of local stations or boxes adapted to interchangeably receive individually characterrzed keys for actuating the impulse imparting devices within the local stations or key boxes, whereby circuits'are closed connecting the selected local station with its corresponding indlcator in the main station and for subsequently closing the main circuit through such connected local and main stations.

With the foregoing and other objects inview, the invention will be more fully described hereinafter, and will be more par- {ucularly'pomted'out in the claims appended iereto.

Referring to Sheet 2 of the drawing, designates local stations or key boxes which may be of any required number and are adapted to be placed in different locations, suchas upon different floors of a building and in different wings or sections of the building for establishing local stations at known points throughout the building. Each local station 25, see Figure 1, is electrically connected to a selector 26 which is arranged at preferably some convenient por-- tion of the building and may be located in the office of the telephone switchboard operator. -These selectors 26 cooperate with a common selective contact ring 27 ,see Fig. and the latter has electrical connection with indicators 28, see Fig. 1, which may be of any desired number and which have their fixedcontacts in the ring 27.

Each local station or key box 25 comprises a body casing of suitable size and configura+ tion adapted to be mounted in or upon a wall and which may be generally of the construction of the usual outlet box. Mounted within the box or body 25, see Fig. 3, is a frame 29 for supporting the mechanism and which preferably has an upwardly ofls'et bottom portion 30 forming a guide for supprovided with ing block straps 40,

vporting a pair of rack bars 31 and 32 arinopposlte sides of the casing The casing carries a transverse shaft 33 upon which is mounted a pair'of sleeves 34 and peripherally notched discs 36 and 37 respectively adapted to turn with the sleeves upon the shaft 33- and having pinions 38 on thesleeves meshing with the racks 31 and 32 for movement thereby.

Extending longitudinally in the upper part of 'the casing, as shown, is an insulator support 39 carrying contact 41 and 42 which are bent U-shape,

ranged and'the contacts and 41 being fitted over the'upper edge of the bar 39 with its side portions at opposite sides of the bar and terminating in different lengths from the top of the bar. The free ends' of the strap 40 terminate in flexible contact strips 43 which are bent outwardly at right angles to the strap 40 and extend forwardly therefrom along the sides of the bar to a point substantially intermediate the ends thereof.

The strap 41 has flexible contact strips 44 which are similarlybent out substantially at right angles to the strap 41 and which profject forwardly therefrom in spaced relation adapted to be meagre with a spring tongue 47 located beneath the block 39 and overlapping the forward end of the strip 45 and normally urged by its inherent tension out of contact therewith. The tongue 47 is adapted to be pressed and retained against the strip 45 for closing the circuit through the strip 45 and tongue 47 by an arm 48 mounted on a sleeve 49 and.

which has a depending finger 50 adapted to be thrust inwardlyfor raising the arm 48 and pressing the tongue 47 against the contact strip 43. The sleeve 49 also has a releasing finger 51 depending in the path of the rack 32 and adapted to be engaged thereby, as the latter moves forwardly in the casing toward its normal inactive position. The finger 50 is of suflicient length to project into the path of a key 52 which is inserted in the key slot 53 formed in the .cover or casing.

The contact strip 46 carries a pair of vi brating tongues 55, one at each side of the block 39 and each'tongue 55 has .upon its free end an enlarged or rolled over portion 56 forming a wiper presenting upper and front wall 54 of the tion 57 in the form of a wiper hearing which extends laterally relatively to the block 39 and engages across the peripheral edge of the adjacent notched disc, 36 or 37. The strip 55 is 43 and 44by the turning of the adjacent disc. The notches or serrations formed in the periphery of the disc correspond to the number and time intervals of the closing of the different circuits in ,which the strips 43 thus vibrated between the strips and 44 are included. Each disc 36 and 37 is independently urged into a position of rest by a spring 58. see Fig. 3, having one end secured to the frame 29 and its other end secured to the adjacent sleeve 34 and The rack bars 31 and 32 are thus normally urged forward and rest against the outer end or face plate of the casing. The frame 29 is provided with another transverse shaft 59, see Fig. 4, upon which is mounted to turn a sleeve 60 having at one portion a depending projection 61 which lies in'the path of the forward end .of the rack 31 so that the rack, .when returned to normal position of rest, strikes the finger 61 and turns the sleeve 60 accordingly. The sleeve 60 has end of the frame 29.

near its other end a depending and rearwardly projecting locking dog 62 adapted to cooperate with a ratchet disc 63 mounted upon the sleeve 35 and with the teeth of the disc 63 facing forwardly toward the nose of the dog 62. A light spring 64 normally urges the dog 62 against the ratchet 63 for locking the disc 37 from turning after the rack bar 32 has been moved inwardly by the key 52.

The face plate 54 of the casing is .provided with the key slot 53 of desired con-- figuration and which accommodates the barrel of the key and the latter is preferably centered between the rack bars 31 and 32 by a centering pin 65 projecting from the rear The key 52 has at opposite sides flanges 66 and 67 which may be varied in length according to .the individuality of the key and which are adapted to engage at their outer ends the forward eX- tremities of the racks 32 and 33 for retract ing the racks to various extents according to the distances through which the notched discs 36 and 37 are to be turned. This variablefoimation of the flanges 66 and 67 is -'indicated in Fig. 6 by dotted lines as at 68 and 69 showing the flanges 66 and 67 of different lengths.

WVhen the key 52 is inserted in the slot-53, the key being centered on the pin 65 is forced inwardly until the flanges 66 and 67 engage the forward ends of the rack bars 31 and 32. As soon as thiscondition arises the rack bars are carried backwardly with the key and the discs 36 and 37 are rotated until the key 52 reaches its innermost position. As the key 52 approaches its innermost po sition the detent or projection 70 on the inner side and at the top of the barrel of the key strikes the finger 50 and swings the sleeve 49- to raise the arm 48 against the spring tongue 47 and thu close a circuit through the contact 45, tongue 47 and vibrating strips 55. When the sleeve 49 is thus turned the releasing finger51 is also swung with the sleeve inwardly into the path ofthe forward end of the rack 32, the

rack having first been retracted by its key flange 67.

By a mod fied arrangement of the component parts the mechanisms could be operated by inserting and rotating the actuating key.

The key 52 is now withdrawn. Y The pawl "62 holds the disc 37 from turning but the spring 58 of the disc 36 is permitted to immediately actuate the disc to turn it toward its normal position of rest. The resultis that the undulated peripheral edge of the disc 36 causes the vibration of the stri 55 between the contacts 43 and 44 and thus alternately closes the circuit through these contacts and through the branch circuits" which include such contacts. When the rack bar 31 approaches its normal position 63, permitting the other spring 58 to oper ate its disc 37 toward a normal position of rest. The disc '37 causes the vibration of the other spring contact 55 between the spring contacts 43 and 44 at the other side of the block 39. Thus the circuit from the main contact 42, connected to wire 71, is alternately closed inthe branch circuits of the contacts 43 and 44, connected respectively to wires 72 and"74. The rack bar 32, on approaching its normal position of rest, strikes the finger 51 and swings the sleeve 49 in a direction to move the arm 48 down and release the spring tongue 47 from the main contact strip 45, thus opening the main circuit. The parts are now in position of rest and ready for insertion ofthe same or another key having the flanges 66 and 67 of desired length. The lengths of the flanges 66 and 67 determine the distances through which the discs 36 and 37 are turned, and consequently the number of impulses or vibrations effected by the alternate closing of the main' circuit through the branch circuits.

Referring now to Figs. 1 and 4, particularly, it will be noted that the local station or key box has the main contact, 42 and 45, connected to a main wire 71, while the upper branch contact 40 is connected to wire.7 2 which leads to the actuator 73 of the selector 26 and the lower branch contact 41 is connected to a wire 74 which leads directly to the selector 26.

lUlB

contact 43- and wire 72,-qthe actuator 73 is operated to adjust the selector 26. As shown in Fig. 7, particularly, the actuator comprises a magnet mounted in a suitable frame 75 carried on the top of an insulating board or casing 76. The magnet 73 is grounded in a wire 77 which leads to a battery 78 constituting the source of electric energy for operating the various devices of the system. The magnet 73 has an armature 79 normally urged by a spring 80 away from the extremity of the core'of the magnet and against a suitable stop 81 determining the outer position of the armature. The armature carries a pawl 82 pivoted to the free end of-the armature and adapted to actuate the selector.

The selector comp-risesa rotary contact member 83 mounted upon the board 76in proximityto the pawl 82 and provided with a ratchet wheel 84 with which the pawl 82 engages for intermittentlv advancing the The member 83 is of rest.

(led groups of three each of contacts 93 which correspond in number to that of the keys 52 and which compose the substantial or body portion of the selected cont-act ring 27. These groups 93 of contacts also correspond in number to the number of indicators 28 employed at the central or main station, and arranged coaxially and concentrically within the ring 92 is a pivoted arm 94 provided with a gear wheel 95 by means of which the arm 94 may be turned to traverse the groups of contacts 93, and a spring 96 is connected at one end to the. arm

94 and at its other end to the board 7 6 for normally urging the arm 94 into aposition Th means for operating the arm comprise three magnets 97, 98 and 99 having respectively the armatures 100, 101 and 102 normally urged into a position of rest inspaced relation from the cores of the magnets by their respective springs 103, 104 and 105. V are mounted upon a frame 106 supported upon the upper portion of the board 7 6 and provided near its opposite lower corners with upstanding rests or stops 107 upon which the end armaturcs 100 and 102 normally rest. The gear wheel 95 is connected to a suit-able train of gearing 108 comprising any suitable number of correctly proportioned gears and pinions and including ratchet wheels 109 and 110 arranged to be engaged by pawls' 111 and 112 respectively,

the pawl 111 having connection with armature 102, while the pawl 112 is connected to armature 100. The ratchet 110 also serves as a means for locking the train of gearing 108 from retrograde movement after adjustment of the arm 94. This is eflected bymeans of a locking dog 113 pivoted at one end to an extension 114 of the frame 106v the locking dog 113 out of engagement with its ratchet.110 to release the train of gears 108. The spring 105 is compressed by such action and the spring is of U-shape with its ends overturned and engaging the pawls 111 and 112-for the purpose of swinging said pawls in opposite directions and out The 'armatures and springs '94 forwardly.

member is advanced by. the actuator 73 to ea ers wardly away from their respective ratchet wheels to clear the same. Under such conditions the spring 96 is permitted to oper-. ate for returning the arm 94 to its normal position of rest and turning the intermeshing train of gears 108 therewith.

The rotary contact member 83 is connected to the wire 74, and by its rotation is adapted to selectively include the contacts 86 to 91 in circuit with the Wire 74. The first contact 86 is connected to the magnet 99 for actuating the pawl 102.' The second contact 87 is connected to the magnet 97 for actuating the armature 100. The third contact 88 is connected to a wire. 116 which leads to the arm 94 and terminates in a contact piece 117 seated, in the outer end of the arm. The arm 94 has three contact pieces 117 adapted to wipe against the inner face of the ring 92 and to traverse the groups of contacts 93. The fourthcontact 89 is connected by wire 118 to the middle contact piece 117 of the arm 94, while the fifth contact is connected by wire 119 to the re- I maining contact 117 ofarm 94 for tran mitting the current from the selected wires 116, 118 or 119 to the corresponding con-- tacts in the groups 93 for purposes which will hereinafter appear. 1 The sixth contact 91 is connected by a wire 120 to the central magnet 98 which is closed in the circuit by operation. of the magnet 73 when the impulse imparting disc 36 begins to move after being released by the key 52. which is transmitted to the selector energizes the magnet 98 and restores the arm 94 to initial position so as toprimarily reset the indicators and the selectors into their zero positions before making a new call.

The first impulse therefore When the rotary contact member 83, see v Fig. 7 is moved to place one of its arms or fingers 85 upon the contact 86, and animpulse is transmitted through wire 74, the

' magnet 99 isenergized with the result that the armature 102 is raised to turn the ratchet 109, operate the train of gears 108, and consequently swing the arm 94 .a corresponding distance. impulses be transmitted through the contact 86, the armature 102 Will be correspondingly vibrated to thus intermittently step the arm When. the rotary contact spective indicator 28 in communication with ,Should a number of successive the local station or box, the rotary contact member 83 is advanced,first to rest upon contact 88when the position of the indicator is normal, then stepped to contact 89 to transmit impulses through wire 118, for operating the tens on the indicator, is then moved to contact 90 to transmit impulses through wire 119 for operating the units on the indicator 28. The rotary contact member is then advanced to the final contact 91 whereby further impulse energizes the releasing magnet 98 and returns all of the parts of the selector to normal position resetting the arm.

At the main station, such as indicated in Fig. 9 at 121, there may be a cabinet or casing containing a plurality of indicators 28. Each indicator is of the type specifically shown in Figs. 10, 11 and 12. Each indicator has a main frame 122 in the upper part of which are'mounted magnets 123, 124, and 125. The magnets are grounded at one side in the wire 77. while the magnets are respectively connected to the wires 116, 119 and 118. The frame 122 carries a transverse rod 126 upon the opposite end portions of which are pivoted armatures 127 and 128 which project across the forward ends of the cores of magnets 123 and 125 respectively and are normally urged away from the pole pieces of these 'magnets by springs 129. i

The free ends of the armatures 127 and 128 have pivotally connected thereto forked pawls 130 and 131 which project away from the magnets and normally engage ratchets 132 and 133 respectively. The ratchets 132 and 133 are mounted on a pair of sleeves 134 which are arranged to turn upon a transverse shaft 135 secured in the frame 122 and the sleeves 1.34 have upon their adjacent inner ends each a number or indicating wheel 136 operating adjacent a space 136" in the face of the station box containing the number or name of the particular individual being located. Each sleeve 134 carrie; upon its outer end portion a toothed wheel 137 adapted to be engaged by a locking dog 138 arranged to hold the sleeves 134'in advanced position subsequent to each operation of the adjacent pawl 130 or 131. A transverse shaft 139 is arranged in the frame 122 and carries a pair of locking pawls 140 which project between the forked arms of the' pawls 130 and 131 and engage the ratchets 132 and 133 and which are normally urged against the ratchets 132 and 133 by springs 141.. and which, upon turning of the shaft 139. may be lifted out of engagement with the ratchets 133.

The pawls 140 have projections 142 which engage beneath the forked pawls 130 and 131 to lift the same out of engagement with the ratchets 133 upon the turning of the shaft 139. The shaft 139 carries armatures 143 which are arranged in proximity to the core of the magnet 124 so that when the lattubular shaft 139' are rotated sufficiently-to lift the pawls 140 and the parts connected thereto for releasing both of the sleeves 134.

The pawl-s 138, are arranged to hold the sleeves 134 from racing forward under'impulses of the pawls 130 and 131 and are raised and lowered by the rocking of the sleeves 139 when raised by travel of the pawls 140 over their respective ratchets 132 and 133.

In operation and use of this annunciator or indicating system, the same may be installed in a building, ship or manufacturing plant of considerable size with the local statlons or key boxes 25 arranged on different floors and also in different wings or sections of the building. Doctors, nurses, or attendants may each be provided with an 1ndividual key 52, the keys being built on some system, such as that illustrated, where they are distinguished onefrom the other in the lengths of the flanges 66 and 67. Eachkey box has one of its discs, suchas the disc 36-, provided for the most part with a smooth peripheral edge but'having a. corrugated or undulating section adapted to transmit impulses to one of the indicators 28 after the selected. indicator has been coupled with the local station or key box being operated upon.

When a person desires to announce at the central station his whereabounts in the building, it is only necessary that theperson insert his individual key 52 into the nearest local station or key box, push the key into the box to the full extent, and then withdraw the key therefrom, no further 0 eration being required on the part of the person.

When the key is inserted in the box the flanges 66 and 67 engage therack'bars 31 and 32 in proper sequence and slide the same inwardly to the various degrees required and dependent upon the lengths of the flanges 66 and 67. This action, as before described, turns the discs 36 and 37 and places the same in positidn for subsequent As the key approaches its innermost position the projection or lug 70 of the key strikes the finger 50 and closes the main cir- As, the key I cuit through the switch box. is withdrawn the disc 36 is first set in operation to cause the intermittent closing of the.

circuit through the wires 72 and 74 for opi 4 crating the selector so as to connect one of the indicators with the operated local station, and such operation depends upon the individual formation of the key so that by observing the selected indicator the erson having the key 52 will be determined. As soon as the disc 36 has completed its operation, the disc 37 is then permitted to operate under tension of its spring 58 so as to trans- \mit impulses to the selected indicator, such operation of the indicator showing the specific local station which is set in operation.

In the selector 27 the arms 94 may be arranged in closely spaced apart relation as there is an arm 94 for each actuator 7 3 and the latter correspond in number to that of the local stations 25.

From Figures 4 and 5 it will be noted that the discs 36 and 37 of the local station have certain lobes higher than others.

These higher lobes elevate the contact pins 57 sufficiently to close the upper contacts 43 and 56 and send an impulse through the wire 72 and magnet 7 3. This latter magnet 73 is actuated only when it is desired to shift the wheel 83 of the selector to control .the movements of the arms 94 and the number The disc 37 of the key box has its peripheral edge so formed as to step the selector to the next contact after the desired number of tens has been indicated on the tens wheel 136 for closing the circuit through Wire 118. Further impulse energizes magnet 125 and causes the unit wheel 136 to be advanced as desired; As soon as a desired number is reached the further automatic operation of the key box actuates the selector to close the circuit through wire 119 of the magnet 124, thus actuating the armatures 143 and releasing the number wheels 136. The number wheels are then returned to normal position under tension of their springs 134. 7 l have illustrated and described a preferred and satisfactory embodiment of my invention, but it is obvious that changes may be made therein within the spirit and scope thereof as defined in theappended elanms.
